The practical details should be figured out in a decade or so. The political side may be harder.

Are they all understood? Sure, it seems like a rational suggestion, and we know that if we add it to the atmosphere it should cool, but what other effects will it cause? How many times have we tried this trick where we introduce something new to an environment and it doesn't turn out like we'd like it to? Feels like we're hoping to apply a band-aid but not deal with the wound.
We know a lot about it because volcanoes do this occasionally. Temperatures cool down for about 2 years, which is how long it takes for the S02 to break down.
Considering that the stratosphere is part of the atmosphere, that's both pedantic and incorrect.

Volcano's don't pump pure SO2. Yes, the science may be entirely valid, and it's not for me decide, but I think it warrants heavy consideration before we try to solve problems we're creating due to adding excess by adding additional excess.

Doesn't SO2 sink in air? Because we'll need to be constantly adding it to the atmosphere aren't we going to end up with acid rain as it falls to the ground?
Either way, if acid rain is the price for controlling global warming, I think that is a very desirable trade-off!
